Train drivers union ASLEF will take strike action on Tuesday 7 May severely impacting Southeastern services.
Most routes and stations will be closed and there will not be any replacement buses.
Southeastern is urging customers to only travel if absolutely necessary.
In addition, strikes on neighbouring operators means that travel into and around London will be difficult.
Trains that are running are expected to be very busy, there may be queues outside stations, and services will be starting later and finishing much earlier than usual.
Southeastern services will run on the following lines only:
- Dartford to London via Bexleyheath
- Dartford to London via Sidcup
- Highspeed between Ashford International and London St Pancras International
Between Orpington and Charing Cross
All other lines will be closed, and no replacement bus services will be provided. Online journey planners are up to date with detailed travel information.
Scott Brightwell, Southeastern’s Operations and Safety Director, said: “We are only able to run a very limited service due to the ASLEF strike on 7 May and our advice is to only travel if absolutely necessary.
“Trains that are able to run may be very busy and there could be queues at some stations. Services will start later in the morning and finish in the early evening.
“There is also strike action across other operators so please check your entire journey if you have to travel.
“We’re really sorry for any inconvenience this causes but we will run a full service on all other days.”
ASLEF also announced an overtime ban from Monday 6 May to Saturday 11 May. Southeastern expects to run a full service during this time, except for Tuesday 7 May,.
